Optimização de um sistema de arrefecimento solar térmico para um edifício de serviços no sul da Europa
| Resumo: | The building of BRISA Operation Control Center combines high indoor climate control performance standards with low environmental impact. The building skin has solar thermal energy collecting surfaces installed in the façade, taking advantage of the local climate’s high solar availability. These surfaces perform several tasks: thermal energy collection for the cooling and heating system, shading of the building external skin and improvement of the thermal and acoustic insulation. As expected for a building with high internal loads in a mild climate, cooling is the main requirement. This building has a single cycle absorption cooling system to use the cooling potential of the solar collecting surfaces. This work presents the main aspects of the design process and resultant indoor climate control system, including software simulation results and details of the most innovative parts of the building ventilation and energy exchange systems. The main road traffic control room, and a set of connected offices, uses displacement ventilation in a raised floor configuration with inflow in the room perimeter. The building and climate control system design relied on software thermal simulation (EnergyPlus, including a developed displacement ventilation model). This simulation proved essential in devising the control strategy for the energy production system. The predicted solar fraction for the solar power air conditioning of this building was higher than 60%, being the remaining from backup system (chiller/heat pump). |
